' Our invention has for its object to furnish an improved machine for forming horseshoes, which shall beso constructed and arranged that the'hot bars may be fed in at one end of the machine and come out at the other end in the form of perfect shoes; and

It consists in the construct-ion and combination of various parts of the machine, as hereinafter more fully described.

' A represents the frame-work ofthe machine.

B is the drive-shaft, which revolves in bearings attached to the rear part of the frame-work A, and to which power is applied in the ordinary manner.

To the shaft B is attached a small gear-wheel, b, the teethof which mesh into the large gear-wheel G,

attached to the short shaft D, that revolves in bearings attach ed to the forward part of the frame A.

To the shaft 1) are attached, or upon it are formed, two cams, E, with which are connected the rods F by the straps f.

The lower ends of the rods or bars F are pivoted to the slide-G, which moves up and down in grooves or ways in the frame A.

To the slide G are secured the die H, by which the propcrlength is cut from the bar, and the dies I, by which pieces are cut from the edge of the bar forming the calks, and bringing thepiece out from the bar into the form shown in fig.

The die H is so formed as to cut the bar in such a way as to leave the end of the piece cut off in about the form required for the end of the shoe, and the end of the bar in about the form required for the end of the next shoe.

The dies H I pass down through holesin the stationary die-plate, and should enter a water reservoir, so as to be cooled after each out.

The. cutters of the dies II I are formed upon the forward sides of the bodies of said dies, and are so formed as to leave a way or space above said cutters, for the bar or shoe to be fed forward through, while the lower parts of the dies are in the water, shown in fig. 9. I

The bar, when being operated upon, is placed in a groove, in the forwa-d part of the bed-plate of the machine, and is fed forward from one set of dies to another, by the sliding bar J, which slides in guides attached to the said bed-plate.

To the inner side of the bar J are attached smali dogs 6rpawls K, which, when the bar J is being drawn back, slide over the pieces of the bar, or rather the partially-tbrmed shoes, -'and drop down attheir rear ends, so that the said pieces are carried forward by and with the said bar in its forward movement. the movements of the bar J being so regulated as to leave the said pieces in the exact positions for tin-m tobe operated upon by the dies.

The dogs or pawls K are thrown down at the rear ends of the said pieces or shoes, by small springs 7: attached to the said bar, and connected with the said dogs or pawls.

The stopping of the pieces or shoes at the exact point required is further insured by the stops L, which pass in through holes in the front edge of the bedplate,and the outer ends of which are pivoted to arms M, attached to the rock-shaft N, which works in bearings attached to the front of the bed-plate or frame-work, and which is operated at the proper tim in the manner hereinafter described.

To the inner end of the shor shaft D is attached a small bevel-gear wheeliO, the teeth of which mesh into the teeth of the small bevel-gear wheel P, the journals of which revolve in bearings attached to the frame-work A of the machine, and to one of said journals is attached a cam, Q.

It is a bar, .the lower end of which is pivoted to the end of the connecting-bans, by a screw or bolt passing through one or the other of the holes in the adjacent ends of the said bars 1% S.

, .The other end ofthe bar S is pivoted to the sliding feedbar J.

The upper part of the barRis pivoted to the frame A, andto its upper end is attached, or upon it is formed, the unequal armed cross-head T, which is made in about the form shown in fig. 1, and to the upper end of which is pivoted a friction-roller, against which the cam Q acts, the effect of which action being to push the feed-bar J back.

To the other, or lower end of the cross-head T, is pivoted the lower end of the bar U, the upper part of which is slotted, to receive a pin, 1 attached to the outer side of the cam Q, which pin q strikes against the bottom of the slot in the said bar U, to move the sliding bar J forward with a. quick move-- ment to feed the pieces or shoes forward tothe next set of dies.

The back movement of the .sliding feed-bar J is vmade as the dies are being drawn back, and the forward movement or feed is made while said dies are stationary or advancing to their work.

. Asthe pieces or shoes are moved forward to their places, the small cam (1 formed upon the base of the camQ, strikes the fi'iction-roller of the cross-head T, and moves the feed-bar back a very little, to keep the dogs or pawls K out of the way of the dies.,

To the drive-shaft B is attached a second small gear-wheel, l), the teeth of which mesh into the large gear-wheel V, attached to the short shaft W, which revolves'in bearings attached to the lower real-part of the frame'A. I

To the shaft V are attached two cams, X, for operating the two sets of dies Y Z and A that finish the ends, and countersink and complete the nail-holes of the shoes.

The dies Y round off and finish the ends of the shoes, and the dies Z, which are'attached to the same plate with the dies Y, countersink and form the tapering parts of the nail-holes, the formation of the nailholes being completed by the dies A,'attuched to another die-plate, and at a subsequent operation. The cams X act against the rear edge of the die-. plates B, or rather gainst friction-rollers X, pivoted to the said rear edges, to force the dies Y Z A forward to do their work.

The die-plates B are moved back by the bent levers C, which are pivoted at their angles to a bar, D, attached to supports secured to the lower part of the frameA, and the upper ends of the forward arms of which strike against stops or projections E, formed upon or attached to the under sides'of the die-plates B. v The ends of the rear arms of the bent levers'O are slotted, to allow' the cams X to pass through them, and are operated, to draw the die-plates B back, by the pins it", passed through said camsX, and projecti-ng upon both sides of said cams, as shown in figs.

2, '3, .and 11.

To the driving-shaft B is attached a third small gear-wheel, b, the teeth of which mesh into the teeth of the large gearwheel F, attached to the outer end of the 'short shaft G.

The shaft G passes through and WOIKS in hearings in the upper forward part of the frame A, and passes through vertical slots in the sliding frame H, and has a triple cam, 1, formed upon or attached to it, the middle part of which strikes against the top crossbar, or rather against a friction-roller, h, pivoted to the-top cross-bar of the sliding frame H, to raise said frame.

The side parts of the cam I strike against frictionrollers, 7t, pivoted to the lower part of the sliding frame H, to force said frame downward, to bend the shoe into the desired form.

J K is the die or former, by and around which the shoe is bent or formed.

The die J K is made in two parts, an inner part, J, which is stationary, and which is rigidly attached to or formed solidly upon the forward side of the lower part of the sliding frame H, and an outer movable part, K, which is secured to the outer end of the stem L, which passes in horizontally through a hole in the lower part of the sliding frame H.

The rear end of the stem L is slotted, or has a slotted bar attached to it, through which slot passes the stationary standard M, through a slot in which passes a pin, 1', provided with a friction-roller, and attached to the slotted part of the stem L.

The upper part of the slot in the standard M is inclined forward. as shown in fig. 18, so that, as the sliding frame H is moved up and down, the said inclined part of the slot in the standard M will move. the movable part K of the die J K forward, to drop the completed shoe, and back again to its working position, ready to form another shoe.

The rear end of the stem L moves back and forth in a guide-support, It, attached to the sliding frame H, and which is provided with friction-rollers h, placed above and below the stem L, and which also rest against the front and rear edges of the standard M, to diminish the friction in the various movements of the said parts, thus relieving the guides of the sliding frame H from all lateral strain while forming the shoe, the outward pressure upon the part K and the inward pressure upon the part J' of the die being sustained by the standard M.

The die J K, in its up-and-down movement, passes through a notch in the groove through which the shoes pass, to be operated upon by the various dies. The middle part of the piece or shoe to be operated upon, lies across this notch, and is forced into and through it, by the descent of the die J K, the edges of the said notch, against which the shoe hears, being provided with rollers to diminish the friction.

N is the lower die, which is made in two parts, pivoted at their outer ends in recesses in the frameor bed-plate of the machine.

The inner ends or jaws of the die N are held up and open to receive the shoe by the springs O, placed beneath them in the recess in which they work.

a is a projection or toe, attached to or formed upon the side of the lower point of the one part and overlapping the point of the other part, and which performs the double purpose of a guide, to keep the two parts always in line with each other; and, second, to give form to the toe-scarf of the shoe.

As the shoe is forced down into the die N, the die N is also forced downward,closing the jaws of said die and forming the shoe, which jaws are again opened by the action of the springs 0, when the. die J K is again raised, allowing the said die J K and the completed shoe to rise out of the said die N.

To the inner end of the short shaft G is attached small gear-wheel, P, the teeth of which mesh into the teeth of the small gear-wheel Q, attached to the end ofthe short shaft 1%, which revolves in bearings attached to a standard, a, attached to the forward side of the frame A, directly opposite the centre of the set of dies by means of which the formation of the nail-holes is completed. I

To the shaft- R is attached, or upon it is formed, va. cam, S, with which is connected the upper end of'the connecting-rod T, to the lower end of which is pivoted the socket-plate U, which slides up and down in ways or grooves in the standard a, and to which is secured the punch V, by which the toe-scarf is formed in the shoe.

The punch V has a hole formed in it, with which is connected a. small tube or pipe, 1:, the other end of which should be connected with some suitable waterreservoir, to keep the said punch V cool.

To'the projecting end of the shaft R is attached, or upon it is formed, a small cam, \V, upon which rests the lever X, the inner end of which is pivoted to the standard a, and to its outer or forward end is pivoted the upper end of the connecting-bar Y, the lower end of which is pivoted to the arm Z attached to the rock-shaft N, that operates the stops L, as hereinbefore described, so that when the shoulder of the lever X drops from the shoulder of the cam W,

the rock-shaft N will be rocked or operated by the spring or springs A", connected with one or more of the arms M of said shaft, and pressing against the frame A of the machine.

As the lever X is raised by the cams the stops L will be again withdrawn.

Having thus described our invention,

We claimas new, and desire to secure by Letters Patent 1. The combination of the stationary guide-standard M, slotted as shown, the sliding die-stem L, dies J and K, and sliding die-plate H, substantially as herein shown and described, and for the purpose set forth. 7

2. The device for operating the sliding feed-bar J, formed by the combination of the cam' Q51 q, pushbar U, cross-head connecting-bar T It, and connecting-bar S with each other, and with the said feeding bar J, substantially as herein shown and described, and for the purpose set forth.

3. The combination of the die J K, constructed and arranged to operate as described, with the die N and sliding frame or plate H, substantially as herein shown and described, and for the purpose set forth.

4. (lon'ibining, in a single machine, the dies for cut-- ting off the bar, forming the calks, punching the nailholes, forming the toe-scarf, and bending and finishing the shoe, substantially in the manner herein shown and described.

5. The hollow punch V, for forming the toe-scarf, in combination with the other parts of a horseshoe machine, substantially as herein shown and described.

The above specification of our invention signed by us, this 4th day of September, 1869. l
